SWIVEL WRENCH.

Refiled for abandoned application Serial No. 619,071, filed February 14, 1923. This application filed August 16, 1926. SeriaI No. 129,542.

The device forming the subject matter of this application is a wrench of that general type which is used for supporting drill bits of the kind used in connection with well drilling operations, whilst the drill bit is being assembled with the rod or other element which carries the bit.

The structure embodies a support, a carrier mounted to tilt on the support, and a rotatable member journaled in the carrier. The invention aims to provide novel means for supporting the rotatable member antifrictionally upon the carrier, to improve the construction of the rotatable member and, generally, to improve and to enhance the utility of devices of that type to which the invention appertains.

WVith the above and other objects in view, which will appear as the description proceeds, the invention resides'in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in side elevation, a device constructed in accordance with the invention;

Figure 2 is a broken away;

Figure 3 is a section on Figure 2; and

Figure 1 is a plan of the carrier.

The wrench forming the subject matter of this application embodies a support, denoted generally by the numeral 1 and including a handle 2 and diverging arms 3 located 1n a common plane with the handle. At the place of juncture between the handle 2 and the arms 3, an eye 1 is located, the same being adapted to cooperate with suspension means 5 whereby the support 1 may be upheld during the operation of the tool.

The wrench includes an annular carrier 6 extended between the arms 3, and shown in clearest outline in Figure 4. The arms 3 carry pivot elements 7 whereon the carrier 6 is mounted for tilting movement. The carrier 6 is supplied with an opening 8, located at the outer ends of the wrench, the opening being closed by a gate 9, pivoted at 10, at one end, to the carrier 6, the cartop plan wherein parts are the line 3-3 of rier being supplied with a latch 11, which coacting with the other end of the gate, holds the gate in a closed position. In its upper surface, the gate 9 has an arcuate groove 12, there being an arcuate groove 14; in the upper surface of the carrier 6, the grooves 12 and 14 being located in a common circumference. Pintles 15 extend transversely of the carrier 6 and of the gate 9 and are mounted therein, the pintles 15 passing across the grooves 12 and 14. Disklike rollers 16 are journaled on the pintles 15 and are disposed in the groove 1.4: of the carrier 6 and in the groove 12 of the gate 9, the rollers projecting upwardly a slight distance above the upper surface of the carrier and above the upper surface of the gate.

The numeral 17 marks a rotatable member, which may be a composite structure, comprising a body 18 of circular outline mounted to fit closely but rotatably within the carrier 6. The rotatable member 17 includes a cap plate 19 superposed on the body 18 and connected thereto by securing elements 20, the cap plate projecting outwardly beyond the periphery of the body 18, as shown in Figure 3, to form a flange 21 for which the rollers 16 coact. A notch or seat 22 is fashioned in the top plate 19, and the body 18 of the rotatable member has a correspondingly shaped notch 23.

The operation of a tool of the sort depicted and described in well known to those skilled in the art, but it may be stated, briefly that by opening the gate 9, the drill bit or other tool may be inserted into the. cooperating notches 22 and 23 of the cap plate 19 and the body 18 of the rotatable member 17. The tool is upheld by the suspension means 5. The body 18 of the rotatable member 17 is provided with depending outwardly inclined grips 24, through the instrumentality of which the operator may rotate the member 17 The rollers 16 constitute a means for upholding the member 17 anti-frictionally for rotation. Since the rollers 16 are located not only on the carrier 6, but, as well, upon the gate 18, the rotatable member is antifrictionally supported whilst the flange 21 is moving across the gate. The body 18 of the rotatable member 17 is of a common diameter below the flange 21, and, consequently, the rotatable member may be lifted out of the carrier 6 freely, the pintles 15 constituting means for maintaining the rollers 16 assembled with the carrier when the rotatable member is lifted out of the carrier.

This application, Serial No. 129,542, is filed in the place of my former application No. 619,071, filed Eebruary 14-, 1923, and forfeited by reason of my failure to pay the final Government fee, or renew the application, within the time prescribed by law.

lVh at is claimed is In a wrench of the class described, a support including a handle and arms, a carrier mounted to tilt on the arms, agate movable on the carrier, the carrier and the gate being provided with cooperating grooves, pintles mounted in the carrier and in the gate and extended into the grooves,

rollers in the grooves of the carrier and of the gate and permanently held therein for rotation upon the pintles, and a rotatable member located within the carrier and provided with an outstanding flange coacting with the rollers, the rotatable member being provided in its edge with a seat, and being of a common diameter below the flange whereby the rotatable member may be lifted out of the carrier freely, the pintles constituting means for maintaining the rollers assembled with the carrier when the rotatable member is lifted out of the carrier.

In testimony that I claim the foregoing as my own, I have hereto afiiXed my signa* ture IVALTER E. WIESENTHAL.
